BATTERY CONNECTORS Filed Jan. 21, 1955 United States Patent i BATTERY CONNECTORS Joseph K. Schaefer, Hollywood, Calif.

Application January 21, 1953, Serial No. 332,271

3 Claims. (Cl. 339275) This invention relates to storage battery connectors, and more particularly to a fixed body on a battery post with a simple connect and disconnect principle.

Among the objects of the invention is to provide a simple battery connector that will eliminate all the present day disadvantages by reason of the following:

First, to provide a connector which has all exposed materials made out of non-corrosive materials.

Second, to provide a connector that will fit all present day battery posts.

Third, to provide a connector which connector body is secured to the battery post by soldering or other means of suitable practice.

Fourth, to provide a connector which allows the disconnection of the connector and the battery cable.

Fifth, to provide a connector that utilizes present battery cables, by allowing for the application of a terminal lug, or the use of cables that are equipped with lug terminals on both ends, or the fashioning of a loop directly from the copper stranded wires of the battery cable itself.

Sixth, to provide a connector that will do away with special present day tools, terminal pullers, terminal pliers, terminal reamers and terminal spreaders.

Seventh, to provide a connector that once secured to the battery post requires no further attention, eliminates hammering on terminals, broken battery posts and posts squeezed out of shape, due to present yday terminals.

Eighth, to provide a connector that maintains perfect electrical continuity due to 360 degrees of contact surface around post, and permanently sealed members one to the other.

Ninth, to provide a connector which incorporates the use of highly conductive materials in the circuit connection, and a non-conductive protector housing to cover this material.

Tenth, to provide a suitable connector whereby a system of interchangeability of batteries is possible with this connector and present day terminals.

The invention together with its objects will be best understood from a study of the following description taken in connection with the accompanying drawings, wherein:

Figure I is a top plan view of my preferred battery com nector, with part of protector housing broken away to show a preferred detailed connection by bolting means.

Figure Il is a side view of my preferred battery connector, with part of the protector housing broken away to show interior parts of the connector and detailed bolting means.

Referring to the drawings by reference numerals, particularly to the form o-f the invention shown in Figures I and II, it will be seen that connector body 1 is adapted to tit down on a battery post 2 and is provided with a bore 8 having a restricted bottom which receives and engages an intermediate portion of the battery post 2.

The restricted portion of the bore 8 forms a oor with a hole to receive a batterypost, and is adapted to embrace the battery post circumferentially. The battery connector is thenper'manen'tly secured to the battery post by soldering or by the use of- Vany/"other suitable means. In Figures I Zas part of the connector, either special bar material imbedded into the connector body'orA part of the"co`nnector by reason of tlie"sar`nerriat`erial.f Thel'battery cable 7 'having had, the protector housing 6 slipped. ontothe cable 7 and -awayl froin'the endiof the cable, so as to'aifect the application of a cable lug. In Figures I and II there is shown a prefered cable lug now commonly in use today which has been affixed by soldering or crimping. This preferred cable lug 5 has a attened Wall section 15, which meshes in between the projecting bars 3. The bars 3 and the flattened Wall section 15 of the cable lug 5, have an axially aligned 'hole to receive the bolt 4. The bolt 4 is slipped through this hole and lockwasher 14 placed over bolt 4 outside of bar 3 face, after lockwasher 14 the nut 13 is threaded on to the bolt 4 and securely tightened by a wrench or wrenches. The protector housing shown in Figures I and II, of my preferred battery connector is of a yielding material. This protector housing 6 is pushed along the cable 7 in the direction of the connector. The circular lip 16 of the protector housing 6 is forced over the ring face 12. By pushing, the protector housing lip 16 will pop into the circular groove 10 and stop against face 11 of connector 1.

It will be noted from Figure Il that circular ring 12 is diametricaly smaller than circular face 11 of connector 1.

From the above it will be seen that I have provided a battery connector which may be readily and easily applied to a battery post. That many of the parts are commonly in use today and easily obtainable. Due to the many different shaped lugs in use today, this problem has been anticipated. The advantage of placing the projecting connector bars otf center materially aids in the use of these different shaped lugs, as they can be placed on the outside face of the connector bars, and a flat washer placed between the bars before applying the bolt assembly.

It is further anticipated that in some instances a fashioned loop directly out of copper stranded wires of the cable itself will be attempted. This means too will work, by placing the fashioned loop outside of the connector bar and under the lockwasher after having placed a flat washer in between the projecting connector bars before the bolt assembly is applied.

It is thought that the construction, utility and advantages of a battery connector embodying the features of the present invention will be appreciated without a more detailed description thereof.

Having thus described the invention, what is claimed as new is:

1. In a battery connector for permanent connection to a battery post, a connector body having a bore therethrough restricted at one end for receiving and engaging an intermediate portion of said post, said bore serving as a receptacle for solder to secure said body permanently to said post, an extension formed integrally with said body and extending therefrom substantially normal to the axis of said bore, and insert conductor means having a section thereof embedded in said body and a section thereof embedded in said extension and a further section extending from said extension for connection to a cable, at least a portion of said body embedded section of said insert conductor means lying substantially in the surface of said bore to form a path for current to low direct from said cable through said insert conductor means to said solder and o thence to said post.

2. A battery connector as set out in claim 1 wherein Patenteda Aug; y21', 1956 said insert conductor means comprises a pair of transversely spaced substantially parallel bar members having axially aligned holes therein for receiving a fastener to secure said cable thereto.

3. A battery connector as set out in claim 1 wherein said extension is shaped to receive one end of a resilient sheath ihaving its other end overlying said cable to seal the connection between said insert conductor means and cable from said post and connector body.
